TO ALL WHOM IT MAY CONGERN:

Be it known that I, GEORGE BRUCE, of Corydon, in the county of Harrison, and State of Indiana, have invented a new and useful Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification.

The pump embraced in the present invention is intended more especially for the pumping or forcing of heated wat-er, although it can be applied to other uses.

In the common hot-water pumps lthere isa great complication and intricacy of elbows and other parts, rendering it impossible to remove the deposits of lime which cause so much trouble in the majority of s ucll pumps. My improved pump, however, is simple in construction, it consisting of a. hollow cylinder easily examined, cleaned, andrepared, which cylinder is provided with two plungers, having but a short stroke, and operated so as -to produce the greatest amount of work. In the accompanying plate of drawings my improved pump is illustrated'- Figure 1 being an elevation'cf the front side of the same, and

Figure 2 a vertical section taken in the plane of the line x x, iig. 1.

Similar letters of reference indicate like parts.

A, in the drawings, represents the pumping cylinder, placed in a horizontal position, and open at each end. This cylinder A, upon its lower side, communicates, through a centre valve or valves, opening inward, with the `water-reservoir or supply, and at its upper side, through a valve or valves opening outward, with the discharge pipei'or tube B inserted therein. C, two plungers or piston-heads, arranged to play in cylinder A from each open .end to its centre line. These plungers C have each a rod, D, secured to them, that play through guides, E, at their outerends, and by the connecting-rods F, hung or pivoted to them, they are both operated by the camway, or groove G in the face of a disk or plate, H, attached to a shaft, I, provided with a crunk-handle or other suitable means for turning it, the connecting-rods by the r'ollers L hung-to the upper ends playing around and withinthe said cam-way or groove, which is of suitable shape to cause the plungers or piston-heads to smultaneously move in and out Within the cylinder, and thus to pump and force up the water rthrough the discharge pipe or tube D. l

I claim as new, and desire to secure by Letters Patent- The cylinder A, piston-heads C, cam-grooved disk H, and connecting-rods hung in said cam-groove, when allare constructed and arranged together, substantially as and for the purpose specified.

GEORGE BRUCE.
